Abstract

一种双灯丝灯泡,在玻壳内的灯丝支架上并联两根钨丝,当其中一钨丝断掉另一根钨丝仍发挥照明作用,尤其夜晚照明时钨丝突然断掉且无补救措施的情况下优势突出,延长了灯泡寿命,提高利用价值,是一种简便的照明灯泡。

Description

双灯丝灯泡
本实用新型属电器用品,具体涉及一种双灯丝灯泡的结构。
通常灯泡内只有单根钨丝,这种灯泡使用一段时间灯丝断掉后只能丢弃,若是在夜晚照明时突然灯丝断掉且无其它措施的情况下将是一片黑暗,给生活带来不便。
本实用新型的目的在于:设计一种双灯丝灯泡,即使其中一根钨丝断掉而另一根钨丝仍发挥照明作用,延长了灯泡使用寿命。
本实用新型的目的是这样实现的:在灯泡玻壳内的支架上并联连接两根钨丝。
图1为本实用新型的结构示意图
图中:1玻壳、2支架、3钨丝
下面结合附图介绍本实用新型的实施方法:
在玻壳1内的支架2上并联连接两个阻值相等或不等的钨丝3,在打开开关后能同时发光。当其中一根钨丝断掉时,剩余的另一根钨丝仍可保持一定的照明状态。
本实用新型结构简单、延长灯泡寿命、节约开支,特别适合灯泡易损坏的公共场所如广场、楼梯走道等,是一种比较理想的照明灯泡。
